Abstract

A stylus printing head comprising a number of electromagnets which operate the printing styli and which are clamped on a conical carrier by means of a clamping device. The carrier comprises cradle-shaped, resilient supports for each of the electromagnets. The resilient supports compensate for differences in expansion of the electromagnets, the carrier and the clamping device in reaction to temperature variations occurring. The resilience of the supports is obtained by means of slots in the carrier which enable the use of a plurality of carriers in the same printing head. [US4350450A]
